Today GreenTek Solutions will be guiding you through the entire process of resetting a Cisco 3750 Series switch. This might be necessary for several reasons such as: if you've forgotten passwords, you're repurposing the switch for a different network or department, or you want to reset it to factory defaults.

Regardless of your reason, our complete guide has got you covered. We’ll go step by step, making the process as clear as possible. –

Step 1

To start, you'll need to connect your computer directly to the switch using the console cable. Once you've physically connected the switch to your computer, launch your terminal emulation software and open a new connection.

Step 2

Power on the switch. When it starts booting up, you'll see text scrolling on your terminal emulation software. Interrupt the boot sequence when "The system will autoboot now" appears.

After all, press either the Break or Esc key on your keyboard. This will stop the boot process and take you to a 'switch:' prompt, which is the ROMMON mode (ROM Monitor).

Step 3

When prompted with 'switch:', enter 'flash_init' and hit the enter key to initialize the flash file system.

Step 4

At the prompt, type 'dir flash:' and press enter to see all files stored in the flash memory of the switch.

Step 5

Upon encountering a file named 'config.text', input 'rename flash:config.text flash:config.old' and press enter. This command effectively changes the name of the configuration file, thereby eliminating the current configuration settings.

Step 6

Type 'boot' and press enter to boot the switch without any pre-existing configurations.

Step 7

After the switch has booted, you'll see a 'Switch>' prompt. Then, type 'enable' and press enter. This will put you in privileged EXEC mode, as indicated by the 'Switch#' prompt.

Step 8

Rename the configuration file back to its original name, type 'rename flash:config.old flash:config.text' and press the enter key.

Step 9

Enter 'copy flash:config.text system:running-config' and hit the enter key.

Step 10

Use the 'configure terminal' command, employ the 'enable secret' and 'enable password' commands to establish new passwords.

Step 11

Once you've set your new passwords, type 'write memory' or 'copy running-config startup-config' and press enter.

Congratulations! You have successfully reset your Cisco 3750 Series switch.
